Document Summary
Has cellular elements, a matrix (plasma) and fibers. Most of the time blood doesn"t have fibers --> only when blood clotting happens. Meet all three requirement of connective tissue (ct) Elements (not cells, not complete elements, called formed elements. Rbc w/o nucleus platelets have clotting factors but cytoplasm, membrane and vesicles only fragments. Dependent on saturation of oxygen (scarlet when o rich, dark red when o poor) Starts off with a nucleus to make haemoglobin then ejects nucleus --> central depression. More viscous than water --> plasma proteins giving viscosity ph 7. 35-7. 45. This is constantly monitored --> acidosis and alkalosis. Affects the range of the cells inside and around blood. About 8% body weight, more in males than females usually. O2 from lungs, nutrients from gi to cells. Metabolic wastes from cells to kidneys and lungs. Temp: distribution, conservation, dissipation ph in body tissues (plasma ptns, bicarbonate) Acidosis and alkalosis --> the carbonic anhydrase conversion system.
